Success lies in the right combination

No matter which scraper type you want to use, the mode of operation employed by our scrapers is ingeniously simple: an especially developed polyurethane body, cast around a stainless steel supporting tube or shaft, fits closely against the conveyor or roll surface and responds to product flow with great flexibility.

If you need a scraper to remove highly adhesive residue from the conveyor or roll, select a harder scraper lip. Softer materials are recommended for less adhesive products since a softer scraper lip is even more responsive to irregularities in the conveyor or roll surface.



For most applications, our scrapers are made of polyurethane. In addition to the proportion of raw materials and the reaction conditions, the properties of these polyurethanes are mainly determined by the polyols (polyester or polyether polyols) that are chosen. These thermoplastic polyurethane elastomers offer precisely those characteristics that are important for our scrapers and crucial to their functionality:

  • Food compatible
  • Flexible in a wide temperature range (-20 °C to +60 °C)
  • Extremely wear-resistant
  • Highly resistant against buckling and tearing (high edge tear and tear propagation resistance)
  • Good resilience
  • Good dynamic loading capacity
  • Good to very good resistance to weathering
  • Oil, grease and solvent-resistant
  • Hydrolysis and microbe-resistant (in the polyether versions)

Regardless of the application, our scrapers are produced in the hardness range from 75° to 95° shore A.


Straightforward installation

In order to achieve the required pressing force of the scraper against the conveyor, we use a maintenance-free torsion element integrated in the supporting tube. This type of positioning permits a space-saving design and also protects the torsion element against external influences. A double O-ring system creates a seal between the torsion element and supporting tube for optimum protection against the penetration of dirt and product residue.
